Beschreibung
Zusammenfassung:	The collector has a transparent cover (1) exhibiting transmission-and/or reflection characteristics that are changeable depending upon temperature of the collector and/or light intensity and/or external electrical voltage. The transparent cover comprises transparent disks (4, 6) and/or shading unit (5), which is attached as coating on the transparent disks. The shading unit comprises fluid, gel or solid, tungsten oxide, vanadium-oxide and reversible photochromic material. The cover comprises colorant solar cells with low colorant concentration. The shading unit comprises a reversible hydrogen switchable mirror-system, reversible polymer dispersed liquid crystal system and reversible suspended particle device.
